Fortunately low voltage in a cell does not cause dentrits to grow it is the charging and cycling process esp with high current that does.
This is attributed to the evolution of Li metal morphology during cycling, which leads to dendrite growth and surface pitting. See https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5126712/
My personal thoughts and beliefs:
Assuming that dendrites offer a resistance factor till they pierce the membrane and short the cell I believe that IR is affected negatively. I.e. Higher.
Additionally the surface area of the Anode is compromised resulting in poor performance hence capacity loss which we measure with our testers.
As with you I have no documentation for that belief.
